Construct a list of integers from highest to lowest in python
I am trying to develop a small mouse application. It should get the coordinates (X, Y) and put the cursor there.
The problem is when trying to go to the X coordinate less than the current one.
import win32con
from win32api import GetCursorPos, SetCursorPos, mouse_event, GetSystemMetrics
from time import sleep
def clickWithCursor(xDesired, yDesired):
xCurrent, yCurrent = GetCursorPos()
slope = float(yDesired - yCurrent) / float(xDesired - xCurrent)
def goAhead(x, y):
for x in range(min(xCurrent, xDesired), max(xDesired, xCurrent), 2):
y = int(slope * (x - xCurrent) + yCurrent)
SetCursorPos((int(x), y))
sleep(0.002)
mouse_event(win32con.MOUSEEVENTF_LEFTDOWN,x,y,0,0)
mouse_event(win32con.MOUSEEVENTF_LEFTUP,x,y,0,0)
return goAhead(0, 0)
def main():
clickWithCursor(243, 184)
main()
The above is a very bad attempt at doing it, which doesn't give me the result I was looking for. I've looked all over how to do this and just couldn't find the right path.
In short, I want to create a list so that it follows logically from larger to smaller, or smaller, according to the order of the parameters.
So, if I were to give the range (4, 1) that I want to cast to: [4, 3, 2] or the range (1, 4), it wouldn't think and build the correct path ...
EDIT: I refactored the code as per the answers and made it more readable for other users to view. Notice the "sequence" method in the MouseController class:
from win32con import MOUSEEVENTF_LEFTDOWN, MOUSEEVENTF_LEFTUP
from win32api import GetCursorPos, SetCursorPos, mouse_event
from time import sleep
class CursorPositionPrinter(object):
"""docstring for CursorPositionPrinter"""
def print_cursor_pos(self):
print GetCursorPos()
def __init__(self):
super(CursorPositionPrinter, self).__init__()
class AutoClicker(object):
"""docstring for AutoClicker"""
def click(self, times):
xCurrent, yCurrent = GetCursorPos()
for i in xrange(times):
self.simple_click(xCurrent, yCurrent)
def simple_click(self, x, y):
mouse_event(MOUSEEVENTF_LEFTDOWN, x, y, 0, 0)
mouse_event(MOUSEEVENTF_LEFTUP, x, y, 0, 0)
def __init__(self):
super(AutoClicker, self).__init__()
class MouseController(CursorPositionPrinter, AutoClicker):
"""docstring for MouseController
Controlls your mouse magically!!!"""
def sequence(self, a, b, n):
mn, mx = a, b
step = -n if mn > mx else n
for value in xrange(mn, mx, step):
yield value
def click_with_cursor(self, xDesired, yDesired):
self.go_to_coordinates(xDesired, yDesired)
self.simple_click(xDesired, yDesired)
def go_to_coordinates(self, xDesired, yDesired):
xCurrent, yCurrent = GetCursorPos()
slope = float(yDesired - yCurrent) / float(xDesired - xCurrent)
for x in self.sequence(xCurrent, xDesired, 2):
y = int(slope * (x - xCurrent) + yCurrent)
SetCursorPos((int(x), y))
sleep(self.latency)
SetCursorPos((xDesired, yDesired))
def __init__(self, latency=0.02):
super(MouseController, self).__init__()
self.latency = latency

either step 1 or 1 whichever is greater after you get min and max:
def up_down(a, b):
mn, mx = min(a), max(b)
step = -1 if mn > mx else 1
return range(mn, mx, step)
Output:
In [9]: list(up_down([4,5,5,7],[0,1]))
Out[9]: [4, 3, 2]
In [10]: list(up_down([0,1],[4,5,5,7] ))
Out[10]: [0, 1, 2, 3, 4, 5, 6]
If min is greater than we need a negative step, if not just use step 1.
To make it clearer to use logic in your own code, you just need to use if / else:
def goAhead(x, y,n=1):
step = -n if xCurrent > xDesired else n
for x in range(xCurrent, xDesired, step):
y = int(slope * (x - xCurrent) + yCurrent)
SetCursorPos((int(x), y))
sleep(0.002)
If you want to change the step size you can pass any n
